You will then combine the flour, baking soda, finely ground black pepper, cinnamon, allspice, nutmeg, ginger, and cloves in a medium-sized bowl. Stir them together and set them aside.
In your mixing bowl, combine the molasses, brown sugar, butter, and vanilla. Cream those all together until smooth. Mix in the egg until it is incorporated. Be sure to scrape the bowl with a rubber spatula.
Mix in your dry ingredients, until just combined. This will make a very stiff dough.
Line a baking sheet with parchment paper.
Using a measuring scoop for equal portions, scoop a tablespoon of dough into your hand and roll it into a smooth ball that is just over an inch in size. Place it on the parchment paper. Continue to roll balls of dough placing them about an inch and a half apart. These cookies do not expand a great deal, so I will bake 16 at a time on a standard-sized baking sheet.
Bake the cookies for 15 minutes, or until the cookies are rather firm to the touch and have little cracks on them.
Allow them to cool for about 10 minutes. While they are cooling, put about a cup or so of confectioner/powdered sugar in a paper sack. After they have cooled 10 minutes, take a couple cookies at a time and place them in the bag. Roll the top shut and give it a shake to coat them. Take them out and set them on a rack to finish cooling.
Repeat the process with the remaining dough.
Enjoy!
Notes
Note: these cookies are very firm. If you feel they are too hard for your liking, place them in an air-tight container with a slice of apple. The moisture from the apple can soften them just a tad.
